TL;DR: In this paper, an ongoing study of the connection between galaxy merging/interaction and AGN activity, based on integral field spectroscopy, is discussed, focusing on the search for AGN ionization in the central regions of mergers, previously not classified as AGNs.

TL;DR: The proposed THESEUS mission as discussed by the authors will vastly expand the capabilities to monitor the high-energy sky, and exploit large samples of gamma-ray bursts to probe the early Universe back to the first generation of stars, and to advance multi-messenger astrophysics by detecting and localizing the counterparts of gravitational waves and cosmic neutrino sources.

TL;DR: In this article, an ongoing survey to study galaxies associated with damped Lyman-α (DLA) systems at redshifts z>2 was presented, where Integral field spectroscopy was used to search for Lyα emission line objects at the wavelengths where the emission from the quasars have been absorbed by the DLAs.

TL;DR: In this article, a source at redshift 1.069 is lensed into four detected images by two early-type galaxies at Redshift 0.388 and 0.8 +/- 0.1.

TL;DR: In this paper, the results of a deep (J ~ 21 mag at 5 sigma) infrared photometric survey of a 0.95 square degree area in the central region of the Upper Sco association were presented.
